android中列表视图中的布局

我有一个列表视图，在其中我添加了一些事件，动态地保存了一些图像。如果我将多个事件添加到同一行中，则根据事件的数量，应该创建多个布局并将其添加到列表视图的特定行中。它是如何做到这一点的。我试过这种方法。但当我向行中添加多个事件时，它与其他布局重叠。请帮帮我

我真的不明白你在说什么，但你应该能够在每一行中使用LinearLayout或其他视图组，这样你就可以添加多个子项。只是要小心；回收行时，您需要在视图组上调用removeAllViews，以便获得新的布局以添加子视图。

ya在添加任何视图之前，我已删除视图。如果我使用相对布局而不是线性布局，那会怎么样呢。。实际上，我的主要目标是在列表视图中动态地向一行添加布局。啊，我明白你的意思了。我认为最好完全在getView中完成工作，然后在数据更改时调用invalidate，从而再次调用getView。否则，上下滚动时可能会丢失添加的视图。这根本不起作用。。我保存了所有视图。但在多个图像的特定行中，它们是重叠的。我想把它们并排展示。然后你可能应该使用LinearLayout
